Mobile 1 5w-30 is notoriously bad oil for these cars. No real 'science' to back this up, but why use it when there are so many other "better" options. Go with Rotella T6 5w-40, full synthetic. It's cheap and readily available at walmart / advance auto.

Ill have to use that when i get my engine back! i never knew about the mobile 1 being "bad" for our cars
